How to define different behaviour when clicking a thumbnails within the same portfolio?
EX: The angular demo page http://www.kriesi.at/themes/angular/template-files/portfolio-4-columns/
-When you click the portfolio-item 'Angular' at the bottom it opens the link in new page
-But when you click any other portfolio-item like the 1st one 'Happy holidays!' it opens a Light-Box; actually clicking the title of the item opens the link in new page but clicking the thumbnail itself opens a light box!
